Patented Sept. 17, 1935 UNITED STATES PATENT OFFICE RECEIVER FOR MATERIALS, SUCH AS ARTIFICIAL SILK Application November 15, 1933, Serial No. 698,180 In Germany November 21, 1932 Claims.

This invention relates to receivers for materials, such as artificial silk and other articial iilamentary products, particularly for the spinning process, the receiver being in the form of u an annular channel or a hoop-like body provided with a circumferential groove for accommodating the material which groove has a small depth as compared to the diameter of the hoop-like body and the cross section of which is provided with raised marginal portions projecting beyond the bottom of the groove.

Owing to the diameter of the receiver being larger' than usual, the receiver is adapted to accommodate a quantity of thread material equal to or greater than spools or other receivers hitherto used, even with the depth of the receiver .being relatively very small, so that the efficiency of the spinning machine can be considerably increased or, if the efliciency is to remain the same, the machine can be dimensioned correspondingly smaller. The difference between the diameters of the outermost and innermost layers of windings of the thread coil accommodated in the circumferential groove of the receiver is so chosen that, in contradistinction to the usual practice, it is no longer absolutely necessary to change the rotational velocity of the receiver during the winding operation, the conoidal drives otherwise required thus being dispensed with. Due to the receiver being of a smaller width, the range of traversing movement of the thread guides is correspondingly decreased with the result that the residual kinetic energy of the reciprocating thread guiding means is reduced and therefore a lighter and simpler design can be adopted for the drive of the spinning machine.

Owing to the said range of traversing movement being decreased, the angular extent of the region through which the thread material moves between the spinning nozzle and the winding position is reduced which permits of raising the speed at which the material is wound on. Hitherto this result could only be obtained by increasing the to another, which was hitherto only the case in the can spinning process, where the artificial silk after being imparted an initial twist is led into a receiving can. The drive can be transmitted to the receiver, according to the invention, in a sim- 5 ple manner, merely by operative engagement oi driving means with the raised marginal portions of the receiver. This driving mode, on the other hand, contributes to simplifying the attendance of the spinning machine during donning and 10 doffing the receivers.

Furthermore, due to the very small depth of the groove as compared with the diameter of the carrier, the lengths of the inner and outer turns are substantially equal and it is, therefore, un- 15 necessary to provide for variable speed winding as is required for ordinary receivers.

In the accompanying drawings several constructional forms of the invention are illustratively exemplied, in which:

Figs. 1 to 7 show different enlarged cross sections of the annular receiver according to this invention,

Fig. 8 shows an enlarged elevation of a further constructional form thereof,

Figs. 9 and 10 show in two views, at right angles to each other, an example of a driving arrangement for receivers similar to that shown in Fig. 8,

Fig. 11 illustrates a drum-shaped receiver partlly in elevation and longitudinal section,

Fig. 12 is a side elevation of Fig. 11, and

Fig. 13 represents a fragmentary section of Fig. 11 on a larger scale.

Referring to the Figs. 1 to 10 of the drawings, 35 I designates generally the receivers the largest dimension of which extends in the radial direction, so that, as will be seen in the Figs. 8 to 10, the diameters A of the bodies of the receivers is a multiple of their depth, that is, of their axial 40 extent, thus being hoop-shaped. This hoopshaped receiver presents an invariable space for accommodating the thread material.

The material of the receiver which may consist to advantage of lacquered aluminium, or acid- 45 or lye-proof steel, or of ebonite, or a similar artiiicial mass is, as shown in Fig. l, of a cross section having a vcylindric middle portion 2 which joins the raised marginal portions 4 by means of intervening outwardly flared sides 3, the cross 50 section thus resembling that of a channel or pf a hollow wheel rim. The marginal portions 4 are formed by heading outwardly the strip of material used for making the receiver and serve for stiffening the same, so that the receiver main- 55 tains its circular shape permanently. By 5 the thread material applied to the receiver is designated.

In the constructional form of the invention shown in Fig. 2, the middle portion or bottom 2a of the receiver is slightly downwardly bowed thus being still approximately cylindrical. Furthermore, in contradistinction to the previous example, the strip of material used for making the receiver is beaded inwardly at the marginal portions [la in the direction towards the middle portion. The sides 3a of the groove are outwardly ared as in Fig. l.

The constructional form of the invention as per Figs. 3 and 321 provides for a circumferential groove of the receiver I, for accommodating the thread material 5b and 5, the cross section of which has two oppositely slanting sides 3b or 3c rising up at uniform inclination from the middle, where these sides merge with a narrow arcuate bottom 2b. At the outer ends, the sides 3D or 3c join with exterior vertical walls 6b and 6C which in turn adjoin the marginal portions 4b and llc, respectively.

The constructional form illustrated in Fig. 4 is distinguished from the immediately preceding one by the feature that the two outwardly flared sides 3d of the receiving groove merge with the marginal portions 4d directly. The shape of the bottom portion 2d of the receiving groove is similar to that of Figs. 3 and 3a.

The constructional form shown in Fig. 5 is developed from that disclosed in Fig. 2 and distinguishes from it in so far that the marginal portions 4e of the receiving groove are formed by separate rings mounted on the body of the receiver. These rings are advantageously made of a material affording considerable frictional engagement for driving the receiver I, for example rubber resistive against acids and lyes.

A similar constructional form, shown in Fig. 6, differentiates from the just described one in that the rings 4f forming the marginal portions of the receiving 'groove are of a different cross section. The shape of the side portions 3e and 3f and the bottom portion 2e and 2f of the receiving grooves in Figs. 5 and 6 is similar to that of Fig. 2.

In the constructional form of the invention depicted in Fig. 7, the receiving groove has a bottom 2g slanting downwardly towards one side thus providing for an unsymmetrical cross section.

In the modified form illustrated in Fig. 8, the groove of the receiver I is approximately of semielliptical cross section, the side walls thus rising up towards both marginal portions at increasing inclination.

All the constructional forms of the invention provide for perforations 'I distributed over the entire circumference of the groove of the receiver I and serving for the eduction of liquids, gases, drying air or the like.

The two marginal portions 4, 4a, 4b, 4C, 4d, 4e, 4f, or 4g, of the receiver I serve as engaging and guiding elements for driving the receiver during its application in the spinning machine, as Well as later on, in the doubling and winding machines. For this purpose the individual receivers I can be inserted in the machine side by side in closely spaced relation, as shown in Fig. 9. For each individual receiver I, two points of support are provided in the machine as indicated in Fig. 10, where each receiver is set to rest with its marginal portions against two roller-like supporting members 3, which are mounted on two shafts 9 one of which at least serves as a driving shaft.

In Figure l0, the reference IG designates the artificial silk thread passed to the receiver I in the direction of the arrow and wound thereabout. The drive of the receiver I can obviously ne reversed, when it is intended to pay out the thread.

In connection with the Figs. l, 2, 5 and 6 it is assumed that the range of traversing movement of the thread guide increases continually according to the increase in thicknes of the coil 5, 5a, 5e, or 5f and in conformity to the taper of the sides of the receiver. In the Figs. l and 2, the shape of the coil assumed by the same, when the material shrinks during drying, is indicated by dotted lines.

The mode of winding assumed in connection with Fig. 3 provides for the range of traversing movement of the thread guide to remain constant lil during the winding operation, so that all the f layers of thread windings 5b are of the same width.

The mode of winding adopted in connection with Fig. 3a differs from the one described immediately above in the respect that the range of traversing movement of the thread guide becomes gradually smaller, so that the width of the layers of thread winding 5c decreases while the thickness of the winding increases. Instead of providing for the individual thread layers of the winding to decrease in width uniformly on both sides, as shown, the width of the winding can be gradually decreased on one side only during the winding operation by correspondingly reducing the range of traversing movement of the thread guide.

'As shown in Fig. Ll, the layers of thread of the winding 5d re all disposed parallel with one of the sides 3d of the receiving groove.

In Fig. '7 all the thread layers of the coil 5g are shown to have the same width.

The receivers I as provided present an invariable space for receiving the thread material are adapted by means of yieldable marginal portions to be pressed snugly against each other dur- 45 ing the after treatment of the thread coils, in such manner, that these portions act as sealing faces against the passage of liquids or gases and the like during the drying. Yieldable marginal portions of this kind are provided in the form of 5 the rings 4e, 4f, or 4g situated at the exterior circumference of the receiver I, as shown in the Figs. 5, 6 and '7. These marginal portions may obviously also serve as closing means of the receivers to the tub used for the after treatment. 5

It is obvious that instead of providing the sealing faces at the exterior circumference these faces may be provided at portions situated radially inwardly on the end surfaces of the receiver.

The receivers described are adapted to be con 6 veyed to the respective working position or from one working position to the other in the empty or filled state thereof, for example by simply hanging them on to a conveyor chain or the like.

The thread material applied to the receiver is at 65 receiving groove of the thread coil 5h. The raised marginal portions h of adjacent receivers I merge with each other to form a closed drum. The divisions between centres of the grooves are chosen to correspond to the distances between adjacent spinning nozzles, so that each groove receives the thread spun by the correlated nozzle. The diameter of the rib formed by two marginal portions is such that the rib projects beyond the finished coil 5h, and the middle portion 2h of the grooves is provided in usual manner with perforations 'I or other suitable passages for the after treatment liquid to penetrate through by pressure action from within the coils 5h or by suction action from outside to inside thereof. The length of the drum is limited by practical exigencies only and can be made for example two meters.

At each end of the drum a rim 5l of a diameter somewhat larger than the diameter of the inner ribs ih of. the receiver I is formed. Furthermore, certain distances apart along the length of the drum, instead of a rib lh rims 52 of equal diameter as the rims 5l are provided. The rims 5l and 52 serve as engagement members for driving the drum in the spinning machine as well as during the aftertreatment of the coils. The rotational or rolling motion of the drum is obtained by means of rollers 8 mounted on shafts 9.

rlhe removal of the drums from the spinning machine and the transporting of the same to the aftertreatment shop is considerably simpler than the corresponding manipulations required for a plurality of individual receivers or spools. The economy of labour obtained is thus very considerable, it being possible to convey a larger number of hoop-like receivers spun with material conjointly by a single manipulation, or else automatically, from the spinning machine to the aftertreatment tubs. The further advantage is also obtained that the receivers need not be sealed individually at their joints, as it is only necessary to seal the ends of. the drum with respect to the vessel in which the aftertreatment of the thread material is carried out. The ends of the vessel for the aftertreatment can be sealed in automatic manner, thus avoiding time-wasting and expensive manipulations and simplifying the means and the performance of the aftertreatment on the whole. The drum presents all the advantages of a single thread receiver, viz. great material-accommodating capacity, neat and but slightly cross wound disposition of the thread material in the grooves and thus elimination of the so-called overruns or cob webs when spinning bands, even wide bands can be Wound on the drum without distortions at the ends thereof, due to the small range of traversing movement of the thread guide provided for.
